Kyrgios slapped with fine after storming off court in Shanghai
Nick Kyrgios has been fined $10,000 (approximately £7,500) and stripped of his first-round prize money after controversially retiring mid-match against Steve Johnson at the Shanghai Masters on Tuesday.
After losing the first set in his first-round encounter with the American, the mercurial 22-year-old walked off court without offering any initial explanation as to why.
He later blamed a stomach bug on his retirement, but did not seek medical help on court, and then defied ATP Tour rules by not undertaking a medical examination afterwards.
As such, tour officials have fined Kyrgios $10,000 for unsportsmanlike conduct and taken away his first-round prize money which amounts to roughly £16,000.
Kyrgios had cut a frustrated figure in the clash and was notably heard complaining about umpire Fergus Murphy's decision-making.
Explaining his withdrawal after the match, Kyrgios said: "I want to apologise to the fans in Shanghai and those that watched around the world on TV today.
"I've been battling a stomach bug for the last 24 hours and I tried to be ready, but I was really struggling on the court today, which I think was pretty evident from the first point."
Meanwhile, Fabio Fognini has been handed an additional fine and a suspended Grand Slam ban for his verbal abuse of an umpire during the US Open.
The volatile Italian was initially fined 24,000 US dollars (approximately £18,000) after he was heard using extremely derogatory and misogynistic language towards Swedish official Louise Engzell during his first-round singles loss in New York.
The World No.28 has been fined an additional 96,000 dollars (approximately £73,000) and banned from two Grand Slams, one of which must be the US Open.
Rafael Nadal continued his winning run while Roger Federer returned to action with a victory at the Shanghai Masters.
Federer ground out a 7-6 (7/4) 6-4 victory over Diego Schwartzman. US Open champion Nadal demolished young American Jared Donaldson 6-2 6-1.
Aljaz Bedene lasted just 12 minutes against Alexander Zverev at the Shanghai Masters before retiring for the second time in two weeks. The British No.2 is struggling with a right knee injury but is continuing to play, and comfortably defeated Paolo Lorenzi in the first round.
